Insulating label stock

Abstract

An insulating label stock includes a thermal insulating layer, which may a fiberfill batt. The batt is laminated to at least one layer of film, paper or fabric. The label stock can be wrapped around a container, such as a can, bottle or pouch. The label stock may be coated with a coating material so that it is printable, thus imparting both insulating properties and print capability to a container.

1. An insulating label stock having a thickness of at least 0.0075 inch and comprising a thermal insulating layer directly laminated to at least one sheet of face material by an adhesive or other means wherein the insulating layer comprises fiber, fiberfill batt, foam, knit fabric, woven material, or fleece material. 
     
     
       2. The insulating label stock of  claim 1  wherein the thermal insulating layer comprises melt blown polyolefin, polyurethane, glass wool, borosilicate, rock wool, polyester, polyethylene or polypropylene. 
     
     
       3. The insulating label stock of  claim 1 , wherein the label stock has a thickness in the range of 0.010 inch (0.025 cm) to 0.040 inch (0.102 cm) and the face material comprises film, paper, and/or fabric. 
     
     
       4. The insulating label stock of  claim 1  wherein the thermal insulating layer comprises polyester, polyethylene, or polypropylene. 
     
     
       5. The insulating label stock of  claim 1 , further including a second sheet of face material on the side of the thermal insulating layer opposite the at least one sheet of face material. 
     
     
       6. The insulating label stock of  claim 5 , wherein the second sheet is a biaxially oriented polyester film. 
     
     
       7. The insulating label stock of  claim 3  wherein the insulating layer comprises polyester, polyethylene, or polypropylene. 
     
     
       8. The insulating label stock of  claim 1  further including a release liner provided on the surface of the adhesive layer facing away from the face material. 
     
     
       9. An insulating label stock having a thickness of at least 0.0075 inch (0.0190 cm) wherein the label stock has laminated thereon a face material by an adhesive or other means, a top edge and a bottom edge; the insulating layer comprises fiber, fiberfill batt, foam, knit fabric, woven material, or fleece; the face material does not affect the thickness of the label stock substantially; and the face material is foam, film or fabric and is sealed together along the top and bottom edges so that fluid cannot penetrate the edges of the insulating label. 
     
     
       10. The insulating label stock of  claim 1 , wherein the label stock has a thermal resistance in the range of 0.05 to 0.5 CLO (0.0077 to 0.077 m 2 ·K/W). 
     
     
       11. The insulating label stock of  claim 9  wherein the face material is film. 
     
     
       12. The insulating label stock of  claim 9 , wherein the thermal insulating layer comprises polyester, polyethylene, or polypropylene. 
     
     
       13. The insulating label stock of  claim 9  further including a coating on the face material, wherein the coating is printable. 
     
     
       14. The insulating label stock of  claim 9  wherein the film is made of a thermoplastic material comprising polyester, polyethylene or polypropylene. 
     
     
       15. The insulating label stock of  claim 9  wherein the face material is modified on the surface facing away from the thermal insulating layer to facilitate printing thereon. 
     
     
       16. The insulating label stock of  claim 9  wherein the face material is modified on the surface facing away from the thermal insulating layer to facilitate bonding to another surface with adhesive. 
     
     
       17. The insulating label of  claim 9  wherein the face material comprises a biaxially oriented polyester film. 
     
     
       18. A container wrapped thereon an insulating label stock as recited in  claim 1 . 
     
     
       19. The container of  claim 18  wherein the container is can or bottle. 
     
     
       20. The container of  claim 19  wherein the label stock has a thickness in the range of 0.010 inch to 0.040 inch; the thermal insulating layer comprises polyester, polyethylene, or polypropylene: and the face material comprises film, paper, and/or fabric.
